Regis hardly has the reputation of a baseball powerhouse. The school’s players don’t go on to major Division I programs or get drafted. In fact, the Upper East Side school doesn’t even have a home field.

“The way we travel around, we call it ghetto ball,” said Conor Dunn, who helped keep Regis’ season alive by driving in the winning run in the bottom of the seventh in a 6-5 win over Xaverian yesterday at Fordham University.

“But we don’t care who or where we’re playing, we’re going to find a way to win.”

So while the Raiders have bounced around from playing home games in Manhattan, The Bronx and even Brooklyn, they may just be developing into one of the CHSAA’s top teams.

They have certainly looked it recently.

One day after upending the league’s top-seeded team, Moore Catholic, the second-seeded Raiders knocked No. 8 Xaverian out of the CHSAA Intersectional playoffs, overcoming a 5-1 deficit in the sixth inning. They will play No. 6 Molloy tonight at 7:00 at St. John’s University. The winner of that game advances to face St. Francis Prep in the championship round.

“We’ve done stuff like that all year long, so we know what it takes,” Dunn said.

Indeed, Dunn knocked in the game-winner earlier in the season against Stepinac after Regis entered the seventh down 5-0.

Yesterday, the hole wasn’t quite as big, but the stakes clearly were much higher.

Sparkplug Tony Negrin led off the seventh with a single to center and got to second when Xaverian flubbed a pickoff attempt. Not long after, the bases were loaded with no one out.

Negrin wound up scoring the tying run on a wild pitch and Dunn followed by slapping a single to left on a full count.

“That was an ugly hit,” Dunn said. “But I’ll take it.”

So will coach Dan Dougherty, who took Regis from the B Division up to the A Division just five years ago. The move has paid off, as the Raiders finished in third place in the city a year ago, fourth the year before that.

“I think people are starting to notice us,” Dougherty said. “It’s not easy with great teams out there like Xaverian, Moore and Molloy, but we’re making our mark.”

That doesn’t surprise senior right-fielder Dunn, who is headed to the College of New Jersey this fall.

“We don’t have any stars, but we have a lot of good ball players,” Dunn said. “I remember a fan in the stands at one of our games in junior varsity told me, ‘You guys just show up, barely have time for infield/outfield, a different field every day and then you beat everybody.’ That’s all we care about.”

It seems to be working.
